On the one hand, docs say it adds extra helpful steps. On the other hand, it works fine here as submitted in the previous patch. What do you think? > Those helpful steps that 'work fine without' are there for a reason, from the documentation:      ‘qt-wrap’           The phase ‘qt-wrap’ searches for Qt5 plugin paths, QML paths           and some XDG in the inputs and output.  In case some path is           found, all programs in the output’s ‘bin/’, ‘sbin/’,           ‘libexec/’ and ‘lib/libexec/’ directories are wrapped in           scripts defining the necessary environment variables. -- quite likely, it won't actually work without -- try "guix shell --pure featherpad -- featherpad" (the --pure is important). Does that work? Greetings, Maxime
